Help with adding percent of total in Access Query

I need to add another column to my query that will show percent of total for groupings chosen below in sex (i.e. Male, Female and No response). It also need to account for the fact that there could cases where there are zeros (i.e. no male respondents to the questionnaire).

the problem is havint the totaL, you could achive this in 2 ways:
but do you need to have this in separate rows?
if yes then
SELECT qryResults.sex, Count(qryResults.sex) AS CountOfsex , Count(qryResults.sex)/total.total * 100 AS percentOfsex FROM qryResults, (select Count(*) as total FROM qryResults) as total GROUP BY qryResults.sex ORDER BY Count(qryResults.sex) DESC;
to get all cases where there are zeros, you need to left join with a table that list all the possible responses. ex
possibility
left join qryResults on
possibility.item = qryResults.sex

SELECT qryResults.sex, Count(qryResults.sex) AS CountOfsex , Count(qryResults.sex)/total.total * 100 AS percentOfsex FROM qryResults, (select Count(*) as total FROM qryResults) as total GROUP BY qryResults.sex, count(qryResults.sex)/total.total * 100 ORDER BY Count(qryResults.sex) DESC;

sorry...
should be better..
again for the null, do you have a table with all the possible answers?
i like to use a table with code/description columns like "M"="Male"

SELECT qryResults.sex, Count(*) AS CountOfsex , (Count(*)*100.0 / total.total) AS percentOfsex FROM qryResults, (select Count(*) as total FROM qryResults) as total GROUP BY total.total, qryResults.sex ORDER BY Count(*) DESC;

Ok, I ran the query and it produced results. However when I try to add a round function, the forms that display the data break and say they can't find the qry. The query works the 1st time when I run it in SQl view and process, but something about rerunning via the form causes issues.

>I do have a table for all answers
then just "left join" it to retrive all answers for the 0% case.
<But something about rerunning via the form causes issues.
What kind of "issue" could you be more specific?

In VBA you can also handle normal files and folders, but zip folders takes a little more - and that you'll find here.
